DNA Cloning/Recombinant DNA/Genetic Engineering

Gene Cloning

1. Biologists take a certain favorable DNA code and construct it to work with a plasmid. After the favorable code is turned, they can replicate it as many times as they like.
2. The DNA from an organism is transferred to this self-replicating bacterial plasmid.This plasmid is a circular, double-stranded DNA molecule that is replicated separately from the bacterial chromosome. This vector can then carry the fragment to the host and start cloning.
3. This can make many copies of one particular gene.
4. I found that the cloning can be used to improve life for some humans. Biologists can take that favorable gene and insert it into a person who does not have that gene or code.
5. DNA cloning is a good thing if it can improve or save lives. Just like giving someone a new heart or liver this can give people another chance at life.
   
   

example of helping to improve life for a human.

Nucleic Acid Hybridization

1. Nucleic acid hybridization is combining two complementary strands in a non-covalent bond. This can happen for DNA-DNA DNA-RNA or RNA-RNA.
2. The hybrids are heated to break the hydrogen bonds between nucleic bases after the strands are separate. The process is repeated to be a longer strand that can be made into a polymerase chain reaction.
3. The process can help find a certain gene in a strand.
4. Nucleic acid can be used to find a gene like in testing
